RAIL-BOND.

Specification of Letters Patent.

PatentedOct. c, 1908'.

Application filed August 4, 1908. Serial No. 446,947.

An object of this invention is to provide a bond which is securely held at the extremities of the rails so as to form a better conducting medium than has heretofore been devised.

A further object of this invention is to provide a device of this character with means whereby the bond will not be severed or injured by the movement of the extremities of them.

The invention further designs a casing which is positioned about therail bond to protect the same from vehicles or the like which frequently catch and break the same from their iastenings.

Other objects and advantages will be apparent from the following description and it will be understood that changes in thespeciiic structure shown and described may be made within the scope of the claims without dcjmrting from the spirit of the invention.

In the drawings forming a portion of this specilicatii'm, and in which like numerals of reference indicate similar parts in the several views, ligurc 1 is a side elevation of the bond and its attachments applied to a rail joint, Fig. :2 is a view of the same havingthe outside casing removed, Fig. '3is a transverse section of Fig. 1, Fig. 4 is an edge view of the bond and the protecting plate, the casing being removed from the same, Fig. 5 is a detailed view of one of the securing members em loycd at the cxtremityof the bond. lieierring to the drawings, and 11 designate the extremities of the rails which are socured together in any well known manner.

The heads of the rails 10 and 11 are apertured as at 12 and 13 into which are inserted the engaging members at the opposite ends of the bond 14. The en aginganembers each iody 15 which is split into several sections at its lower extremity and which carry a head 16 atthe opposite extremity thereof. The head 16 is apert'ured' tends downwardly through the gage against the sides, and 13.

The securing members carried by the bond 14 as well as the bond itself are constructed of copper and are adapted to convey the current across the intersection of the rails. A metallic plate or strip 18 is disposed adjacent to the heads of the rails 10 and 11 which enof the apertures 12 opposite extremities of the plate 18 are recessed to receive the fastenin members which extend into the headsof the rails and support the bond 14.. This arrangement securely holds the late 18in position as well as the bond 14. l olts 19' and 20 are passed through the plate 18 from the inner face thereof havingtheir heads countersunk in said plates for the purpose of-allowing the same to lie closely in contact with the heads of therails 10 and 11. The bolts 19 and 20 are. )ositioned diagonally at the opposite edges of tlic plate 18 and extend outwardly therefrom where they engage through a U shaped casing .21 which protects the bond 14. The casing 21 is provided with a lining of copper 2.; which i'rietionally engages against the bond 14 and acts as a conductor if for any reason the bond 14 should be broken or burned out. The casing. 21 is secured upon the bolts 19 and 20 by nuts 22 which engage the outer surface of the casing 21. The opposite extremities of the casing 21 are bev- -fcled toward the heads of the rails 10 and 11 for the purpose of preventing the engagement oi any portion oi a vehicle or the like which would tend to displace or injure the bond 14.

What is claimed isz- 1. A device of ,the character described comprising a bond, a plate positioned between said bond and a rail joint anda casing disposcd aboutsaid bon 2. A device of the character described comprising a bond, a plate clamped between said mud and a rail joint, a casing disposed about said bond and a copper l-uing carried by said casing. I

3'. A rail bond having means for securing the same to a rail, said means comprising a cylindrical body being split into a of sections at its lower extremity, a read positioned upon the upper-end of said body having an'a )erture formed therein and an expanl sioubolt positioned through said aperture gages upon its outer face the bond 14. The.
